The traditional way of presenting color palettes to users is by rendering these as static arrays of colors. This limits users to staring at color squares to make color-color comparisons instead of engaging them in data mining and critical thinking, activities that promotes discovery and learning—in a research or school setting.
When we developed The Color Miner, we did so with a fractal design strategy in mind. As a result, we developed a tool capable of generating what we call fractalettes or palettes within palettes. That is, each cell of a generated palette behaves as a smaller palette, containing color space information and relationships for the current color.
We could iterate the individual cells for ever, but in practice we found that a one-level iteration was a good start to encourage users to investigate color-color, space-space, and color-space relationships, to find basic trends and information patterns. In general, this architecture can be iterated to organize additional attributes and relational data.
